| 目的 获得中性斯蒂酚酸铅(N-LTNR)在不同高温条件下的贮存寿命，建立一种基于N-LTNR表观活化能和某恒定温度加速性能退化试验的贮存寿命预测模型。方法 以热失重作为N-LTNR性能退化参量，利用恒定温度加速试验方法，获得N-LTNR在某恒定加速温度下的热失重性能退化试验数据，采用线性回归法，获得该温度下N-LTNR的性能退化曲线。结合热失重失效阈值，确定N-LTNR在该恒定加速温度下的贮存寿命。基于N-LTNR热分解活化能，建立N-LTNR在高温条件下贮存寿命的预测模型。结果 采用该模型对某散装的N-LTNR在不同高温条件下的贮存寿命进行预测，确定了该N-LTNR药剂在180 ℃下的安定性出现显著变化，在热失重失效阈值为10%的条件下，得到180 ℃下的寿命为6.4 d；150 ℃下的贮存寿命为86 d。结论 该模型可应用于N-LTNR在高温环境下的贮存寿命预测，为航天火工装置的使用提供了依据。 |

| In order to obtain the storage life of lead styphnate (N-LTNR) under different high temperature conditions, a storage life prediction model based on the apparent activation energy of N-LTNR and a constant temperature accelerated performance degradation test is established. With the thermal weight loss as the performance degradation parameter of N-LTNR, the thermal weight loss performance degradation test data of N-LTNR at a constant acceleration temperature are obtained by using the constant temperature acceleration test method, and the performance degradation curve of N-LTNR at this temperature is obtained by using the linear regression method. The storage life of N-LTNR at this constant acceleration temperature is determined by combining the thermal weight loss failure threshold. Based on the thermal decomposition activation energy of N-LTNR, the storage life prediction model of N-LTNR at high temperature is established. The model is used to predict the storage life of a bulk N-LTNR under different high temperature conditions. It is determined that the stability of the N-LTNR agent changed significantly at 180 ℃. Under the condition of 10% weight loss failure threshold, the life at 180 ℃ was 6.4 days. The storage life is 86 days at 150 ℃. The results show that the model can be used to predict the storage life of N-LTNR under high temperature environment, which provides a basis for the use of aerospace explosive devices. |
